Direct Deposit Forms

Has anyone had to adjust their direct deposit form and move the address down?  I know this is done in Payroll, Modify.  The direct deposit form adjustment is set to 100 for us.  It says to move the address down to enter in a bigger number.  My question is how much of a bigger number do you enter?  I just need to move it down one line.  There doesn't seem to be a way to test this.  Thanks for any help.
